On Rotten Tomatoes, Apostasy has 100% success from critics (Very rarely that critics are unanimous in their approval of a film) and 97% from the audience.
I have loved reading the reviews as they are almost all ex JW's but there is one glaring review that is almost certainly from one active JW who is pleading that the film be banned, even though they haven't actually seen it (typical) and it made me laugh:
